Nyob rau hauv lub neej txhua hnub, screws yog ubiquitous. Nws yog lub hauv paus rau kev ceev txhua yam. Nws yog ib lub cuab tam uas siv cov physics thiab kev ua lej ntawm kev sib hloov ntawm txoj kev sib hloov thiab kev sib txhuam ntawm cov khoom kom nrawm sab nrawm.
Vim muaj hluav taws xob ua kom zoo tshaj thiab hluav taws xob ntawm cov tooj liab thiab txhuas screws, nws tuaj yeem siv rau ntau yam kev siv, xws li kev siv hluav taws xob, khoom siv hauv tsev, teeb pom kev zoo, thiab lwm yam, tab sis tsis muaj ntau yam tshwj xeeb cov ntaub ciav hlau tshwj xeeb nyob rau hauv kev sib xyaw tooj liab thiab txhuas screws hauv Suav teb.
Ua ntej tshaj, txoj cai ntawm kev ua si ua tooj liab hlau thiab steel hlau rods yog zoo sib xws. Lub ntsiab yog vim li cas thaum koj yuav cov hlau hlau thiab cov hlau txhuas, koj yuav tsum tau ua qee yam txiav txim. Koj yuav tsum tau muab cov khoom raw. Koj tuaj yeem muab cov khoom lag luam tsis tau txiav txim. Txwv tsis pub, yog ib qho tseem ceeb uas khib tooj liab pov tseg cov txhuas yuav raug quab yuam. . Secondly, nws yog ib qhov tsim nyog los them sai sai rau txhuas hlau thiab tooj liab hlau. Copper thiab aluminium yog mos heev, thiab txhuas cov chips muaj feem ntau lo rau hauv cov pwm kab noj hniav kom ua rau khawb. Cov khoom txhuas yog qhov zoo tshaj plaws tau muab tso rau ntawm nws cov nplaim rau ib zaj duab xis oxide. Qhov no thiaj li ua rau lub caij nyoog so. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau tshuaj tsuag (khoom, hmoov, thiab) lubricants nyob rau saum npoo ntawm cov txhuas thaum lub sij hawm ntau kom txo cov kab-ploj tuag. Thaum kawg, tsis muaj teeb meem npaum li cas koj sim, nws yuav tsis guarantees kiag li, yog li koj tsuas saib tau ntawm ib lub tshuab ntawm ib lub sij hawm. Thaum twg so, koj tuaj yeem nres thiab tshem tawm cov txhuas cov chips thiab pib ua dua tshiab.
